1. High temperature resistance
High temperature stability: PEEK has extremely high temperature resistance, with a glass transition temperature of 143 ℃ and a melting point of 334 ℃, which can maintain stable performance in high temperature environments. This characteristic enables PEEK military products to function normally under extreme high temperature conditions without thermal degradation or performance degradation.
Long term use temperature: The mechanical properties of PEEK gradually decrease after long-term use at 250 ℃, and rapidly decrease at 310 ℃. This indicates that PEEK military products can be used for a long time in high-temperature environments without affecting their performance.
2. Chemical corrosion resistance
Excellent corrosion resistance: PEEK has excellent chemical corrosion resistance and can resist the erosion of various chemical substances, including most organic solvents and inorganic acids, bases, etc. This enables PEEK military products to maintain stable performance even in harsh chemical environments.
Corrosion resistance similar to metals: PEEK has corrosion resistance similar to nickel steel and can maintain its structural integrity and performance stability in highly corrosive environments.
3. Excellent mechanical performance
High strength: PEEK has high tensile and bending strength, comparable to metallic materials such as titanium and steel. This enables PEEK military products to maintain structural integrity and stability when subjected to high stress or high loads.
Lightweight: The density of PEEK is only about 1.3g/cm ³, less than half of aluminum. Therefore, PEEK military products can significantly reduce weight and improve overall performance while maintaining high strength and durability.
4. Excellent electrical performance
Insulation performance: PEEK has good insulation performance and is suitable for manufacturing military products that require high insulation performance, such as electronic equipment and electrical components.
Dielectric properties: PEEK has superior dielectric properties and can maintain stable electrical performance in high frequency and high temperature environments.
5. Fatigue resistance and wear resistance
Fatigue resistance: PEEK's fatigue resistance to alternating stress is the most outstanding among all plastics, comparable to alloy materials. This enables PEEK military products to maintain stable performance under repeated stress or vibration.
Wear resistance: PEEK has outstanding wear resistance, which can maintain a lower wear coefficient and longer service life in high friction environments.
6. Good processing performance
Easy to process: PEEK is easy to extrude and inject, with excellent processing performance. This makes PEEK military products highly efficient, cost-effective, and able to meet the needs of large-scale production.
In summary, PEEK military products have the characteristics of high temperature resistance, chemical corrosion resistance, excellent mechanical properties, excellent electrical properties, good fatigue and wear resistance, and good processing performance. These characteristics make PEEK have broad application prospects and important strategic significance in the military industry.
